getTupleOutput

Returns an empty TupleOutput instance that will be used by the tuple
binding or key creator.

The default implementation of this method creates a new TupleOutput
with an initial buffer size that can be changed using the TupleBase.setTupleBufferSize(int) method.

This method may be overridden to return a TupleOutput instance. For
example, an instance per thread could be created and returned by this
method. If a TupleOutput instance is reused, be sure to call its
FastOutputStream.reset() method before each
use.
